Topo maps a mess of meaningless lines

Hi. I just purchased a GPS 76csx, and loaded a Canadian topo map on it. But I can't read the map- it's just a mess of meaningless black lines running every which way with no apparent significance.
The map looks fine on my desktop screen, but is useless on the Garmin.
I'm really counting on this GPS on our upcoming canoe trip, can you help, please?
thanks

Sorry for late reply. You need to select an area on your topo map prior to downloading it. For example, if you plan to go to Algonquin Bice Lake (access point 4), then you need to select the map around the area (starting from) Kearney upto the Magnetawan Lake and beyond. Mark waypoints from the put-in to the campsite on Bice Lake (best to compare of the topo and Algonquin canoeing map). Then you can click Transfer, click Send to Device (GPS 76cs should appear) to download it. On the GPS, enter the Find Waypoint button and you should be able to see those waypoints. Good luck for your next trip.

If you have the TOPO maps loaded to an SD card and the card is inserted all you should have to do is go to Tools > Settings > Map > Info in this menu you will find your map sets if you see TOPO make sure it is activated if not you may need to re install them to the SD.

hi peter, firstly the only difference you would notice with topo maps is that the unit will now display contour lines and they will only be visible when you are viewing the map not when you are in the navigation mode.

the contour lines are brown lines on the map that represent different heights above sea level.

In Map Setup page, scroll over to blue 'ball' icon (second from right), press lower left button on side of GPS unit, use Thumb switch to scroll down to "Show None", click Thumb switch in. All maps will disappear. Press lower left button on side of GPS unit again, scroll down to "Show Topo.....", click Thumb switch in. Your Topo maps should now show onscreen.

The reason your Topo map might not have shown is because, if you leave the Navigator map showing, and then just press "Show Topo", the layer showing Topo will still be under the Navigator map. This is why I always tell it to show none, and then load whatever map I need to see onto a bare screen.

You will need to load the MapSource software on your PC then load the maps into MapSource. After the maps are loaded and unlocked you can plug your GPS into your PC with the USB cable and load the maps.

Two possible answers and they are both dependable on the serial number of the map vs.the serial number of the GPS. The best solution is to use Vantage Point to do the transfer. The second method is to directly load the map to an SD card under the directory MAP_DATA and then place in the GPS. Then do a MENU>>VIEW>>MAPS and activate the map. If the map is missing you do not have it under the MAP_DATA directory. If the map shows a RED "X" then the serial number of the map is not the same as the serial number of the GPS.

The preloaded maps are VERY generic, mostly major highways. They are not useful for geocaching.

The good news is that you can download free topo maps created by a very generous Canadian soul, Dale Atkin. The maps are free but donations are accepted. He is also working on US topo maps. I've used Ibycus and Garmin topo maps and prefer the Ibycus version.If this solves your situation, please come back and rate our answer. Thankyou.
